Couple more data points - very low (40 lbs) compression in #1 and non in #3. So clearly there is a problem sealing the combustion chambers - just assuming at this point it's between the head and block, no the rings. And the head to block seal is bad enough that I'm getting water leaking into number 2, 0 compression in #3, and very low compression in #1 and #4.

Potential causes? Bad head gasket install, warped block deck, warped head. And, am I right in assuming it's not the intake gasket or seal as that wouldn't impact the compression ie I could run a compression test without the intake even installed and would still get compression in the combustion chamber right?

And for now I'm taking out the cylinder walls being cracked as it would be unlikely it would affect 3 cyliders? Rings could be bad in all 3, but that wouldn't easily explain the water.

The plot thickens. I'm trying to decide if I should go ahead and take the intake and head off, or if there are other things I should "test" before doing that. Ideas?
